Abstract
The utility model discloses a kind of sealing structure, including skeleton and the elastic component that is attached on skeleton, the skeleton is extended with some projections, skeleton displacement diametrically can be so limited, so as to ensure the quality of production of sealing structure towards axial side.
Description
Technical field
The utility model is related to technical field of sealing technology, more particularly to a kind of sealing structure for bearing.
Background technology
As shown in figure 1, the part sectioned view for sealing structure in a mold.Sealing structure includes skeleton 1 and is attached to bone
Elastic component 2 on frame 1.In sulfidation, skeleton 1 does not only adhere to elastic component 2 towards the inner surface 11 of cavity plate 3.That is bone
The inner surface 11 of frame 1 is contacted with the medial surface 31 of cavity plate 3, so in the axial direction, skeleton 1 can be guided by inner surface 11
Position.But in radial directions, to skeleton 1 without any limitation.Therefore, skeleton 1 is difficult to place in a mold correct
Position, in further sulfidation, the rubber of temperature flowing can drive the displacement in radial directions of skeleton 1.Eventually result in
The rubber being attached on skeleton 1 it is in uneven thickness, or even should adhere on the surface of rubber at some does not have rubber to cover.This
The function and service life of sealing structure can be influenceed.
Accordingly, it is desirable to provide a kind of improved sealing structure is solving the above problems.
The content of the invention
The problem that the utility model is solved is to provide one kind and holds easy positioning of sealing structure in sulfidation.
To solve the above problems, the utility model is adopted the following technical scheme that：A kind of sealing structure, including skeleton and attachment
Elastic component on skeleton, the skeleton is extended with some projections towards axial side.
Further, some projections are uniformly distributed in the circumferential.
Further, during the skeleton is including first end, the second end and between first, second end
Between portion, the projection is arranged on the pars intermedia.
Further, the pars intermedia is coated with elastic component on raised opposite side.
Further, the raised profile is in cylinder.
Further, the projection is formed in the punching course of the skeleton.
Further, the elastic component is rubber.
Compared with prior art, the utility model has advantages below：Skeleton is provided with some projections in axial side, can
To limit skeleton displacement diametrically, so as to ensure the quality of production of sealing structure.
Brief description of the drawings
Fig. 1 is prior art sealing structure part sectioned view in a mold；
Fig. 2 is the utility model sealing structure part sectioned view in a mold；
Fig. 3 is the stereogram of the utility model sealing structure.
Specific embodiment
As shown in Figures 2 and 3, sealing structure includes skeleton 10 and the elastic component 20 being attached on skeleton 10, elastic component 20
Preferred rubber.Skeleton 10 includes first end 12, the second end 16 and the pars intermedia between first, second end 14.The
One end 12 forms the installation portion of sealing structure with a part for elastic component 20, in the second end 16 of skeleton 10, elastic component 20
A part formed sealing lip.
Pars intermedia 14 being coated with elastic component 20 towards the side of punch-pin 30, and in the inner surface 142 towards cavity plate 40 then
There is no elastic component 20 to cover.Further, pars intermedia 14 is extended with some raised 144 from inner surface 142 towards cavity plate 40, if should
Do and be preferably in raised 144 profile cylinder and be uniformly distributed in the circumference of skeleton 10.Certainly, raised 144 profile also may be used
Being other shapes.These projections 144 are formed in the punching course of skeleton 10.Accordingly, if cavity plate 40 is provided with
Dry recess 42 is receiving some raised 144.In the radially opposite sides of recess 42, the inner surface 142 of pars intermedia 14 is interior with cavity plate 40
Side 44 is in contact.Preferably, size of the size of recess 42 more than raised 144, to facilitate installation.
So, skeleton 10 is positioned on cavity plate 40 by raised 144, is limited on axially and radially.Sulfidation
In, even if there is the impact of flowing rubber, skeleton 10 will not also be shifted, the quality final so as to ensure that sealing structure.
In the present embodiment, in raised 144 portions formed between 14, certainly, raised 144 can also be located at skeleton 10
Other positions, the utility model is not any limitation as to this.
Although the utility model is only described with regard to some exemplary embodiments, these description should only as an example and
It is not construed as limiting.In the range of appended claims record, in the case of the utility model spirit and scope are not departed from, respectively
Plant what change was equally possible.
